UNITED STATES BERTRAM LENZEN, OF PROVIDENCE,

IIALF TO GEORGE O. RIIEOKERT,

RING- SPECIFICATION forming part of Letters Application filed April 22,1903.

To all whom it may concern: 5

Be it known that I, BERTRAM LENZEN, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Ring-Trays,of which the following is a specification.

My invention relates to that class of ringtrays which comprisespring-actuated lockingstrips, and is designed to overcome some of thedisadvantages characteristic to structures of this class. The ordinarytray of this type is shown in a former patent to me, No. 710,475. Insuch a structure it is found that the warping of the iioor andcontraction of the metallic locking-strips tend in time to displace thelatter from their channels. The use of a long transverse coiled springfor tensioning the transverse strips induces such an unequal strain thatthe strips do not always perform their functions.

To the elimination of the above defects and to secure additionalfacility of action my invention is primarily directed.

In the drawings herewith, wherein like reference-letters indicate likeparts, Figure lis a plan View of my improved tray with a number of thecushion-strips removed; Fig. 2, a vertical transverse section of thetray on line a: :c of Fig. l, and Fig. 3 a similar section ofA the sameon line g/ y of Fig. 1.

My tray consists of a rectangular body A, with upright walls a. The doorthereof has parallel channels b, in which slide metallic locking-stripsB, shorter than the width of the tray, to allow longitudinal movementtherein of the lockingstrips, whose outer ends traverse the front wallof the box and form handles d. Projections e upon the locking-stripsnear the inner face of the front wall prevent excessive outward movementof the strips. Each of the dat metallic lockingstrips B is provided witha series of prongs f, whose points arel directed toward the 4handles d.One or more retaining-strips w, fixed in the tray-bottom by pins oorpfgil means and transversely disposed in relati to thelockingstrips,retain the latter in their respective channels.

A series of contiguous fabric-covered bars Patented June 30, 1903.

TRAY.

Patent NO. 732,089, dated June 30, 1903.

Serial No. 153,796. (No model.)

t', with intermediate spaces j to receive the rings 7c, rest upon thebottom of thebox at right angles to the direction of the lockingstrips.These bars are transversely traversed by channels Zin their lower facesto allow passage therethrough of the prongs f when the locking-strip isoperated.

A length of spring-wire is looped at its center to form spring-arms h,and the looped portion is fixed to the door of the tray near 6o its backand intermediate the channels b by pins or screws o. As thesespring-arms are intended to tension the locking-strips, the latter areprovided at their rear with rearwardly-directed hooks m, each of whichengages an arm h.

The operation of my device is as follows: When it is desired to insertor withdraw a ring, the locking-strip whose prong corresponds with thering is pressed rearwardly 7o against the tension of the arm h.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. In a ring-tray, the combination with the floor of locking-stripsprovided with engaging prongs and slidably mounted in the ioor, a seriesof contiguous bars above and disposed at right angles to thelocking-strips, posts in `the floor intermediate the lockingstrips, 8olspring-arms upon the posts adapted to longitudinally tension thelockingstrips, and means upon the locking-strips for engaging thespring-arms as described.

2. In a ring-tray, the combination with the l iioor of channels in thefloor, slidable locking strips provided with prongs and resting in thechannels, a transverse strip fixed to the floor and above thelocking-strips for retaining the latter in their channels, parallel con-9o tiguous bars above and at right angles to the locking-strips,stoppinson the locking-strips, and spring means upon the floor adapted to forcethe locking-strips outward as described.

In testimony whereof` I have afxed my signature in presence of twowitnesses.
